Think Bottom Up named as industry collaborators with ICRAR for the SKA project

Think Bottom Up is proud to be named as an industry collaboration partner with the International Centre for Radioastronomy Research (ICRAR) working on the Square Kilometre Array (SKA), which, when complete will be the world's largest radio telescope. The data processing and data management challenge is immense, with the aperture arrays in the SKA producing possibly 100 times the global internet traffic.

ICRAR is evaluating the CEDA technology on which most Think Bottom Up software has been developed, for use in Data Intensive Astronomy. At the core of this technology is a multi-master replicated database based on operational transformation. The technology is the only known solution to solution to the TP2 puzzle that scales.

Introducing CEDA - a platform for collaboration

Today I am pleased to announce the first in a series of white papers that talk about CEDA. What is CEDA? Well, that's exactly what the first paper is about! The abstract of the Introducing CEDA white paper is reproduced below:

CEDA is a high performance database technology that uses Operational Transformation (OT) to support replication and synchronisation for collaborative data entry performed by multiple users. CEDA is an ideal platform for Computer Supported Collaborative Work (CSCW), allowing multiple users to edit that same data concurrently. Users can collaborate in a interactive, realtime manner or work offline and control when changes are propagated to/from other users.

CEDA provides an application development platform for building applications that support collaborative work. Application developers can easily build multiuser applications based on CEDA that are as responsive as single user applications while attaining benefits of realtime interactive collaboration and sophisticated version control. The platform allows for branching and merging of the entire database, supporting manual check-ins, check-outs, updates, tagging and so forth in a similar manner to source code repository systems like ClearCase and Subversion.

The OT algorithms employed by CEDA are extraordinarily efficient, allowing users to work off line for long periods of time and then quickly synchronise with other users.

This paper provides an introduction to CEDA and some of the platforms features.

Think Bottom Up staff have been involved in the research and development of CEDA for the last 12 years or so, though the original research by David Barrett-Lennard goes back further than that. We are very excited about CEDA and the potential of the technology. The collaborative features of CEDA are achieved through the use of Operational Transformation - an area of ongoing research that has gained a lot of press lately thanks to Google Wave.
